POSIX extensions provide a standardized interface for real-time programming, particularly through the POSIX.1b Real-time Extensions. These extensions define features such as priority scheduling, mutexes, condition variables, and timers that are essential for developing real-time applications. However, whether a specific implementation truly supports real-time behavior depends on the underlying operating system and its configuration. Thus, while POSIX extensions offer the framework for real-time capabilities, the actual real-time performance can vary.

What are the different standard in POSIX?
POSIX, or Portable Operating System Interface, encompasses a set of standards aimed at maintaining compatibility between different operating systems. Key standards include POSIX.1, which defines system interfaces and shell utilities, POSIX.2, which specifies shell command language, and POSIX.1b, detailing real-time extensions. Additional standards address threads (POSIX.1c), networking, and security. Together, these standards facilitate software portability and interoperability across compliant systems.
Why is POSIX portable?
POSIX was designed as a standard to enhance portability. That is why it is portable if you use the POSIX standard.
What are the features of rtlinux?
Deterministic Realtime: RTLinux™ supports realtime interrupt handlers and realtime periodic tasks with interrupt latencies and scheduling jitter close to hardware limits. RTLinux reliably give worst case interrupt latencies of less than 15 microseconds on a standard x86 PC, with better figures on single board computers and PowerPC and Compaq Alpha platforms.Standard API:uses a POSIX threads API and follows the POSIX 10003.13 PSE31 ``minimal realtime system model" specification. RTLinux™ runs Linux as its lowest priority thread and provides access to the full power of Linux through a variety ofcommunication methodsOpen Source: FSMLabs RTLinux™ can be freely downloaded from the Internet. The core OS code is available under the GNU Public LicenseRich toolset: All the standard tools-the GDB source level debugger, GNU compilers, Perl, TCL/TK, etc.-are available and easily interfaced with realtime codeSource: FSM lab brochure
